Step-by-step explanation:

Sympathetic nervous system is a type of autonomic nervous system which response in conditions of stress such as threat or injury or fight or flight conditions.

They communicate with the Peripheral nervous system via sympathetic ganglia- pre and post a ganglionic in which pre-ganglionic neurons release acetylcholine in response to stimulus which binds to receptors on post-ganglionic neurons which release adrenaline.
